Why does my iPhone 4S battery die so quickly? - 2

I have an iPhone 4S with the latest update. I turned off location and system services and everything that could possibly be draining the battery, but it still dies fast. According to the usage tab, I have only had my phone charged for 6 hours and it's already at 30% (with a lot of use though). Why does my phone die so quickly?

Depends on a couple of things. How old is the iphone? What stuff you do/do not. For example watching videos will take up more charge, and enpty the charge faster than, say if you were listening to music.3g also takes up a lot of charge. So if you are connected to it all the time, that may be one reason. HTHa bit.

  • Why does my iPhone battery die so quickly? I had my iPhone for about a year and a half, and recently I've noticed that the battery is draining incredibly fast. I've always had it on 3g internet/Wi-Fi and the battery never died this fast so I don't know what the exact problem is. I charged it to 100% yesterday and I only used it for maybe about 10 minutes and left it untouched for the rest of the night. Today when I woke up the phone was dead. I haven't changed the settings or anything fyi.
  • Why does my iPhone battery die so fast? I have boost magic, which is supposed to help my battery last longer, and I kill all my apps when I'm done using them. I go from 100 at 8am and I'm at 60 by 9:30am. And I hardly use it too, just to look up information quickly and I just set my phone aside. I let it go down to 20% battery and let it charge over night. It just started doing this recently. I also keep my brightness to pretty much 0 with the auto brightness on. And it still dies fast. What can I do?
  • Why does my iPhone battery die in 2 hours? My iPhone battery will literally die in about 2 hours. Why is this? I have a iPhone 4S 16gb running 7.0.6… Would buying a new battery and putting it in the phone make it just like new and give me a normal all day battery like what my buddy's get? I'm very frustrated.
  • Why does my iPhone 6 die so quickly now? I dropped my phone and broke it and had to switch to my old iPhone 5c, which had a horrible battery life. I finally got my iPhone 6 fixed, but now my battery dies so much quicker then before. I'm on battery saving mode, I have bluetooth off and my screen brightness is usually down almost all the way. I do listen to music while i'm in school but that has never been a big problem before and all my apps are closed. What's the problem?
